Sorry Benoit. I kind of gave you the short hand version.
RasterLayer.rasterShader() returns the base class of QgsColorRampShader
which is QgsRasterShader() you will have to cast the base class to type
QgsColorRampShader, but don't even know if that is possible in python.
However, there is another way, You could create your own instance of a
QgsColorRampShader and pass that to the raster layer using
>>yourColorRampShader = QgsColorRampShader()
>>yourColorRampShader.setColorRampItemList( YourList )
>>RasterLayer.setRasterShaderFunction( yourColorRampShader )
If you take this approach, you no longer have to call
RasterLayer.setColorShadingAlgorithm().
That should do it. I don't do much python coding, so i may not be able
to highlight all of the differences between the python and c++ approach.
